The early origin of Iguanodontia: new insights into the macroevolution, diversity and biogeography of the clade

open access: yesPalaeontology, Volume 69, Issue 2, 2026.
Abstract Iguanodontia (Dinosauria, Ornithischia) is a speciose group of herbivorous dinosaurs that include the famous genus Iguanodon, one of foundational members of the clade Dinosauria. Despite their very long history of research, several aspects of their systematic relationships and their evolutionary history remain somewhat nebulous.

Study of the combining adsorption-microfiltration process for the treatment of coloured waters

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2012
Generally textile effluents are highly coloured, contain non-biodegradable compounds and they have high content of solid wastes, comprising fibres and paper wastes. The discharge of such effluents in the environment is worrying for both toxicological and

Radar Estimates of Surfzone Dissipation Drive a Morphological Evolution Model

open access: yesGeophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract The dissipation of wave energy is important to nearshore circulation and beach profile evolution. Here, radar measurements of wave dissipation at the water surface across the surfzone are used to estimate water velocities and sediment transport in the lower water column to drive an energetics model for morphological change.

Quantifying Fossil Fuel CO2 Enhancements Along an Urban‐Rural Gradient With Radiocarbon Analysis of Turfgrasses

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 20, 28 October 2025.
Abstract Atmospheric measurements are needed to verify progress in reducing fossil fuel carbon dioxide (ffCO2) emissions, especially in cities where most ffCO2 is emitted. However, measurements of CO2 enhancements alone cannot identify ffCO2 signals due to complexities in atmospheric dynamics and large natural CO2 fluxes.

The Tubotomaculum Enigma and the Rise of Benthic Life During the Opening of the Western Mediterranean Basin

open access: yesGeobiology, Volume 23, Issue 5, September/October 2025.
ABSTRACT Large‐scale geological processes shape microbial habitats and drive the evolution of life on Earth. During the Oligocene, convergence between Africa and Europe led to the opening of the Western Mediterranean Basin, a deep‐ocean system characterized by fluid venting, oxygen depletion, and the absence of benthic fauna.

Climatic and Edaphic Drivers of Soil Organic Carbon and Pyrogenic Carbon Stocks Across Elevation and Disturbance Gradients in Colombian Andean Forests

open access: yesGlobal Change Biology, Volume 31, Issue 7, July 2025.
This study examined soil organic carbon (SOC) and pyrogenic carbon (PyC) stocks in tropical Andean soils across elevation and disturbance gradients in Colombia. SOC stocks to 100 cm depth averaged 433.10 Mg C ha−1 while PyC was 34.13 Mg C ha−1. Key drivers of PyC stocks include soil clay (%), mean annual precipitation (PA), pH, Ca, and NDVI, which ...
